Acoustic Analysis of Bridges

Using a technique known as impact-echo testing, engineers have developed a new method to analyze and evaluate the structural stability of a bridge deck based on the acoustic footprint generated by droplets of water striking the surface.

Acoustic Lens Developed

Inspired by an office toy, researchers have developed an acoustic lens comprised of parallel rows of stainless-steel spheres that could lead to near photo-quality images of internal organs or even "sound bullets" that could be focused to act as sonic scalpels.
